I want to crop a video in HTML 5.

<video id="glass" width="640" height="360" autoplay>
    <source src="invisible-glass-fill.mp4" type="video/mp4">
</video>

The resolution of the video is 640x360, but when I set the width attribute to 200, the video will rescale (retain the aspect ratio). How to crop the video (cut off, say, 220 pixels from both the left and right side) through HTML or Javascript? Is it even possible without cropping the video through video editing software?

I would recommend you to do it with CSS and a wrapper:

HTML

<div class="container">
    <video id="glass" width="640" height="360" autoplay>
        <source src="invisible-glass-fill.mp4" type="video/mp4">
    </video>
</div>

CSS

.container{
    width: 200px;
    overflow:hidden;
    display:block;
    height: 360px;
}
#glass{
    margin-left: -220px;
}

What you could do is use canvas and copy a the portion of the video you like. Here is some reference: http://developertip.wordpress.com/2011/06/04/tuto-html5-how-to-crop-a-video-tag-into-a-canvas-tag/

Responsive video resizing, So how can we crop a video via command line? The amazing ffmpeg utility allows engineers to crop videos with one easy to use filter: #� You can crop the top, bottom, and sides of a clip by using the Crop sliders to remove unwanted parts of the frame. Whatever adjustments you make to a clip, check the clip’s alignment with the others in the sequence. You want to keep your cropped clip centered in the frame for a seamless flow in the sequence. Export and share your video.

I solved the same problem with another approach:

I just cropped the video using an online tool: https://ezgif.com/crop-video

This has 2 advantages:

  1. faster then creating canvases, think about their styling and responsiveness
  2. smaller video file -> less data transfer

  • You tried setting height:auto ?
  • We must define an extra CSS rule to shift the video to the left, in order to make sure that the video is cropped on both sides. We can do it like this: div.container video { margin-left: -220px; }. However, this answer led me to the solution.
  • @MCEmperor yeah you are right. I forgot about that requisite. Nice to know it helped. I'm gonna update the answer with your contribution.
  • Notice that you will need to set the margin-left property of the video tag inside the div.container instead of the margin-left property of div.container itself. You need to edit your answer. div.container video { margin-left: -220px; }
  • @MCEmperor my mistake :) Done.
  • I used position: relative; left: -220px on my video element . I don't know if it's better or worse than the negative margin, but it works.
